Abstract: Traditional manual measurement of optical wedge interference parameters suffers from significant
experimental errors due to human factors,along with operational complexity and low efficiency.This article
proposes an intelligent measurement method to efficiently extract wedge interference parameters. Based on
machine vision and adaptive image processing techniques,the OTSU threshold segmentation is employed to
identify bright and dark regions of interference fringes,and the SUSAN operator is used for edge detection,
enabling precise localization of fringe spacing and accurate measurement. Multiple experimental results
demonstrate that the intelligent measurement system achieves relative errors of all physical parameters below
0.50%,with a response time of only 2.7 seconds per measurement.The intelligent measurement method exhibits
high precision and stability in extracting wedge parameters. It not only enhances students' experimental
efficiency and deepens their understanding of light interference principles but also plays a significant role in
stimulating learning interest and enriching experimental course content.
